Question 1

Accepted characters: numbers, decimal point markers, sign indicators (-), spaces (e.g., as thousands separator, 5 000), "E" or "e" (used in scientific notation).NOTE:For scientific notation, a period MUST be used as the decimal point marker.

Complex numbers should be in the form (a + bi) where "a" and "b" need to have explicitly stated values.

For example: {1+1i} is valid whereas {1+i} is not. {0+9i} is valid whereas {9i} is not.

Suppose an economy is represented by following equations :

Z = C + I + G

C= 300 + 0.9Yd

T = 1000

I = 200

G = 2000

Calculate equilibrium level of consumption for this Economy

Question 2

Suppose that an economy produces two final goods, say

milk and potatoes:

In year 0, it produces 10 pounds of potatoes at a price of $1 a pound, and 5 bottles of milk at a price of $2 a bottle.

In year 1, it produces 15 pounds of potatoes at a price of $1 a pound, and 5 bottles of milk at a price of $3 a bottle.

Nominal GDP in year 0 is therefore equal to $20.

Nominal GDP in year 1 is equal to $30.

What is the percentage difference in growth rates of REAL GDP if we use prices of year 0 and prices of year 1 as the base year price ? (HINT: calculate real GDP for both base years seperately).

Question 3

Suppose that the household nominal income in an economy is 5,000 billion and the demand for money is given by :

Md = Y(0.08 - 0.4i)

Let the money demand is equal to 100 billion.

How much interest rate in percentage value needs to be reduced if the central bank

wants to increase the money supply to 300 billion?
